WAXING AND' POLISEING' HAOHIVNE.

Application led April 3, 1922. Serial No. 549,034.

To all whom t may concern:

Be it known that I, NELSON B. CUTLER, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain Improvements in Waxing and PolishingMachines, of which the following description, in connection with theaccompanying drawings, is a specification, like. reference characters onthe drawings indicating like parts in the several figures.

This invention relates to Waxing and polishing machines and is hereinshown as embodied in a rotary padding brush for spreading wax on heels.

After the heel of a shoe has been scoured, a thin coating of wax isusually applied by means of a heated burnishing iron. The wax isthereafter spread and worked into the surface of the heel by means of arotary brush. As heretofore constructed such brushes have bristles ofuniform length radiating from a hub. When new, the bristles are toostiff to make a good padding brush and require a long period of use tobreak them in. When the bristles have become sui'iciently flexible theythen have a tendency to spread laterally and mat down with the resultthat in a short time the heel comes against the hub and the wax isspread onto the upper. In padding rubber heels another defect of suchbrushes is that the rubber causes the bristles to pull out.

In view of these facts, an object of this invention is to provide animproved padding brush which will obviate the above disadvantages. As afeature of the invention, the illustrated brush is constructed with somelong and some short bristles so that, in use, the longer bristlesimmediately tend to lie over the ends of the shorter ones instead ofspreading laterally. As a result, a better cushioning effect is obtainedfrom the beginning and the brush can be quickly broken in. The resultingrecesses in the periphery of the brush also provide a rumble effectwhich gives a series of slight blows and thereby acts more eiiicientlyin spreading the wax. Withthe ends o the longer bristles overlying theshorter ones, there is less tendenc for them to be pulled out when usedon rubber work. These and other features and advantages of the inventionwill appear from a consideration of the following specification andaccompanying drawings, in which- Fig. 1 is a side elevation of theimproved brush;

Fig. 2is a front elevation;

Fig. 3 is a front elevation with a canvas or other textile coveringapplied to the brush; and

Fig. 4 is a side elevation with the cover partly broken away and showingthe action of the bristles when a heel is being treated.

The brush comprises a hub 4f which is secured for rotation to the shaft6 of a finishing machine. Projecting from different portions of theperiphery of the hub, are clusters 8 of comparatively long relativelysoft bristles, these clusters being arranged in groups. Projecting fromthe remaining portions of the periphery of the hub and alternating with.the longer bristles are a series of clusters 10 of shorter bristles.This construction leaves a series of recesses 12 spaced about theperiphery of the brush so that a rumble eect is produced in spreadingthe wax. It should be noted that the bristles do not extend radiallyfrom the hub but project therefrom in spiral fashion. Consequently, whena canvas cover 14 is put on the brush and drawn against its periphery bymeans of the usual lacin cord, all of the bristles will tend to crow inone direction only and none of them will be crowded in a counterclockwise direction which is here shown as the direction of rotation.

In Fig. 4: a heel 16 is shown applied in working position. As the brushrotates, the leading points 18 on the longer bristles will successivelycontact (through the cover) with the heel and produce a slight blow.This gives a rumble eli'ect which is more eiicient in spreading the wax.The shorter bristles 10 actin the capacity of resilient supports for thelonger ones. In use the longer bristles, under pressure of the work,tend to crowd towards the center and bend 100 over the shorter bristles,bein thereby prevented from spreading lateraly. Although the inventionhas been described by reference to a specific embodiment, it should beunderstood that it is not necessarily limited 105 to the illustratedconstruction;

Having described m invention, what I claim as ynew and esire to secureby Letters Patent of the United States is:

1. In a rota padding brush for Waxlng and polishing t e peripheries ofthe heels of shoes, a rotar hub, separated clusters of long flexibleristles projecting from the hub, and clusters of comparatlvely shortbristles projecting from the hub between the rst clusters and arrangedto form resilient supports for the lon er bristles at a po1nt separatedfrom the ub, the ends of said longer bristles overlying the shorteronesl m use and being held against lateral spreading as they are crowded,towards the center under pressure of the heels thereby preventingcontact of the heels with the hub.

2. In a rotary padding brush for waxing and polishing machines, a rotaryhub, clusters of comparatively long soft bristles projecting spirallyfrom the periphery of the hub. said clusters being arranged in groups,

and clusters of shorter bristles rejecting from the remaining portionsof t e periphery of the hub and alternating with and artially underlyingthe roups of longer c ustersto produce a rum le eiect in spreading wax,the ends of said longer brist es overlying the shorter ones and saidshorter bristles acting as a resilient support for the longer ones andintermeshing with longer bristles to prevent lateral spreading.

3. In a rotary padding brush for waxing and polishing machines, a rotaryhub, bristles projecting from the hub and constructed and arranged toform recesses spaced labout the periphery of the brush, and resilientsupports for the bristles extending from the hub and supporting saidbristles near the ends thereof.

In testimony whereof I have signed my name to this specification.

NELSON B. CUTLER.
